Just a couple of impressions from a guy that was addicted to Destiny, and has played both the closed and open beta of this game:
-Do not like the damage buff to the DZ AI enemies. A little would have been fine, but this buff is very serious. Couple that with the haphazard ways enemies spawn, and you can end up with 2-3 enemies directly behind you while trying to extract. It just reeks of "unfair".
-I think this game is going to cause fights between friends. When Player A is sitting with half an inventory full of purples, and that lovable idiot Player B shoots somebody's drone and goes rogue, you are going to get mad.
-The content drought will be real. Granted I played both Betas, so I've seen everything there is, but fighting the same rotating factions of human enemies and grinding Dark Zone is going to get old super fast.
-The missions are ok, but there haven't been any real "wow" moments so far. Also, I'm sure they're trying to make you use strategies like "fall back" and "flank the enemy" but 99% of encounters are easier done by just camping near the entrance of a given area. Not sure how to get around this, but without the gunplay and maneuverability of Destiny to back it up, I think these are going to get old/boring really quick.
-Loot system feels pretty good. You don't get so much that you're worrying about micromanaging inventory, but you get enough that you're always looking at whatever piece you get.
-Outfits are super depressing. Probably going for the realism thing, but every coat I've got in this beta is either brown, blue, or grey.
Anyways, since my Destiny friends are on board, I'm of course going to play, since 90% of the fun I had in this game is due to them, but I honestly see this one being abandoned way quicker than Destiny.
